HARRY LANSING CAREY, OF RICHMOND HILL, NEW YORK.

DIRIG-IBLE TRAFFIC INDICATOR.

Application 1ed-November23, 1921. Serial No. 517,157.

T 0 all whom t may concern:

Be 1t known that l, HARRY LANSING CAREY,

a citizen of the. United States, and a resident of 'Richmond Hill, county of Queens, and State of New York, have invented certain new and useful Improvements in Dirigible Traiic Indicators, of which the following is a specification.

The object of my invention is to attain a simple dirigible traffic-indicating device of facile manipulative character adapted to the various exigences and requirements of use on road vehicles generally, and particularly suitable for installation on automobiles and analogous motor-driven carriages,

4 trucks, etc.,-an indicator that will be effectiveat night as well as during the clay, as and for the reasons hereinafter fully set fortl1,*the invention consisting in the specific construction,arrangement and combination of parts described and claimed, and distinctive features being the rotative means employed, and the method of attaining internal illumination and the diffusive transmission of light rays, whereby the device is rendered essentially self-contained and semiautomatic in nature and function, substantially as illustrated in the accompanying drawings and exemplified in the text eX- pla-natory thereof, similar reference letters and vnumerals being used throughout to designate the parts.

In the said drawings, Fig. l, is a side elevation of my trafic indicator;

Fig. 2, is a central vertical sectional elevation taken upon plane of line 2, 2, Fig. 8; Fig. 3, is a horizontal section of the pointer head taken upon plane of line -x, Figs. l and 2, only on a smaller scale, and with improved the electric light bulb and other details omitted;

Fig. 4, is a detail elevation of the rotative spindle;

Fig. 5, is a sectional detail of the fixed base post in and on which the rotative indicator spindle is mounted;

Fig. 6, is a transverse section taken upon plane of line 6 6, Fig. 2, looking in the direction of the arrows;

Fig. 7, is a detail of the `iXed base post ca f Fig. 8, lis a top view of my trafHc indicator upon the same scale as that of Fig. 3;

Fig. 9, is a diagrammatic detail indicating t-he positioning of 4my indicating device on an auto-radiator inlet.

My pointer head A, is of arrow configuration, aside from which a distinctive feature 1s the axial illuminative means e, thereof in conjunction with its side light apertures (t, a, arranged convergent` to the central longitudinal line or plane of horizontal rotation, whereby the light emanating from the pointer head A, when the latter is illuminated, will visually indicate traffic conditions or intentions.

Thus, it will be seen by reference particularly to Figs. l and 2, of the drawings, that all the light apertures or slots a, al, are convergent toward the central horizontal line m, and in the direction of the point of the. arrow head, so that at night illuminated slots a., a, will clearly indicate direction of point in accordance with the position assumed by or imparted to the pointer head A.

The latter is preferably made in concavoconvex half sections which may be screwed together as illustrated-in the drawings, or otherwise secured together and upon the upper end of the rotative tubular spindle S, in said upper extremity of which the socket e, for the electric lamp e, is mounted, as indicated more particularly in Fig. 2. This feature of medially and axially positioning the electric light e, Vwithin the rotative pointer head A, is an important factor in my construction and arrangement of parts, in that the light is thereby diffused in both directions, and thus effectually illuminates both the front and rear cavities of the head, rendering the slots a, a, conspicuous and effective for the purpose desired.

The wiring for the electric lamp e, extends through thel hollow spindle S, and may connect with the head light wiring, or with the rear or tail light wiring as the case may be, my indicator being adapted for installation and use at both the front andrear of an automobile or similar motor driven vehicle.

The spindle S, is' rotatively mounted in and upon a fixed base post B, which may be attached to a radiator inlet neck as indicated in Fig. 9, or otherwise permanently positioned at the front or rear of a car, as and by means which may be found most eX- pedient.

A retractile spring R, is interposed between'the spindle S, and the base post B, in such manner that it tends constantly toE hold the said spindle in retracted normal position with the head pointing forward, in which position a stud s, on the spindle S, rests against a fixed part b, on and in the base post B, said fixed part, inthe construction shown by way ot exempliication in the drawings, consisting ot' an arm (b) pendent from the cap piece d', attached to and clos ing the upper end or" said base post B, said cap piece Zi, also acting as a hearina tor the medial portion of the spindle as shown in Fig. 2,-the lower contracted portion s', of said spindle being step-supported on the bottom plug b2, inserted in the lower end of the base post B. In this construction I also utilize the pendent arm b, to lixedly hold one (the lower) extremity of the retractile spring R, in this case consisting of a coiled spring, the upper extremity of which is positioned and held in a filler S3, in the lower portion of the tube-which constitutes the upper portion of the rotative spindle S, also as shown in said Fig. 2, of the drawings.

The spindleS, is manually rotated against the resistance of the coiled retractile spring R, by any suitable means, as by a flexible ligament sx secured to the lower end of the spindle with one' or more convolutions wrapped therearound, saidexible ligament protruding through an aperture b2, formed for the purpose in the lower side wall of the base post 'B, and being of sufficient length to extend to a point and meanswitliin the control of the driver for manipulative purposes.

`What I claim as my invention and desire to secure by Letters Patent is,

l. As an article of manufacture, a dirigible trafiic indicating device of the character designated, comprising a hollow rotative arrowshaped pointer made in concavo-convex half sections formed with light slots convergent to the axial line of pointivedirection, means for clamping said pointer to a hollow rotative spindle, said spindle, and an electric lamp internally posltioned in said pointer in alignment with' its axisof rotation, substantially in the manner and for the purpose described.

ifieraaa 2. As an article of manufacture, a dirigible traic. indicating device of the character designated, comprising a hollow rotative arrow-shaped pointer made in concavo-convex half sections Aformed with light slots convergent to the axial line of pointive direction` means for clamping said pointer to a hollow rotative spindle, said spindle, and an electric lamp internally positioned in said pointer in alignment with its axis of rotation, together with means for rotating said spindle and pointer, substantially in the manner and for the purpose described.

3. As an article of manufacture, a dirigible traliic indicating device of the char acter designated, comprising a hollow rotative arrow shaped pointer made in concavoconvex half sections formed with light slots convergent to the axial line of pointive direc. tion, means for' clamping said pointer to a hollow rotative spindle, said spindle, and an electric lamp internally positioned in said pointer in alignment with its axis of rotatlon, a retractile spring arranged to constantly tend to hold said spindle in normal position, and means' for manually rotating said spindle against the resistance of said retractile spring, substantially in the manner and for the purpose described.

4.. As an article of manufacture, a dirig. ible traHic indicating device of the character designated, comprising Va hollow rotative arr,owshaped pointer made in concavoconvex half `sections formed with light slots convergent to the axial line ofpointive direction, means for clamping said pointer .to a hollow rotative spindle, said spindle,

and an electric lamp internally positioned in said pointer in alignment with its axis of rotation, and manually controlled means for effecting the rotative movement of said spindle and pointer, substantially vvin the manner and for the purpose described.
